Expert writing Tips

Best practice

When using the phrase "by a constant envelope", ensure the context clearly indicates what is being modulated or affected by this constant envelope. Be precise about the subject receiving the modulation.

Common error

Avoid using "by a constant envelope" when you simply mean 'constant'. The phrase implies modulation or influence, not just a static state. Ensure it correctly conveys the relationship between the envelope and the signal or function it modifies.

Linguistic Context

The phrase "by a constant envelope" typically functions as an adverbial phrase, modifying a verb by describing how an action (often modulation or shaping) is performed. As Ludwig AI indicates, it's used to specify that something is influenced by an envelope that remains constant.

Ludwig's WRAP-UP

The phrase "by a constant envelope" is grammatically correct and predominantly used in scientific and engineering contexts to describe how signals or functions are modulated. Ludwig AI suggests that the phrase serves as an adverbial modifier, specifying the manner in which an action is performed, particularly in signal processing. Although "by a constant envelope" may seem similar to "with a constant envelope", the key differentiator is their meaning: "with a constant envelope" describes an inherent property, whereas "by a constant envelope" expresses an influence or action. To avoid misapplication, use this phrase when you are communicating modulation, not merely a static state. The related phrases provided offer alternative ways to convey similar concepts, yet the original phrase remains a precise and specialized term in technical fields.

characterized by a stable outline

Highlights the stability of the outline instead of emphasizing the consistent nature of the envelope.

featuring a consistent perimeter

Emphasizes the perimeter being consistent rather than a general envelope.

having a fixed contour

Stresses the fixed nature of the contour, deviating from the envelope concept.

FAQs

How can "by a constant envelope" be used in a sentence?

The phrase "by a constant envelope" indicates that something is being modulated or shaped by an envelope that remains constant. For example, "The signal is modulated by a constant envelope to ensure consistent transmission power".

What does "by a constant envelope" mean in signal processing?

In signal processing, "by a constant envelope" signifies that the amplitude of a signal is being controlled or shaped by a function that remains uniform over time, which is useful for maintaining consistent signal strength.

Which is correct, "with a constant envelope" or "by a constant envelope"?

Both phrases can be correct but have different meanings. "With a constant envelope" describes something that inherently possesses a constant envelope. "By a constant envelope" describes something that is being acted upon or shaped by a constant envelope.

What are some signals that are characterized by a constant envelope?

Signals like Frequency Modulation (FM) and Phase-Shift Keying (PSK) are types of constant envelope modulation /s/constant+envelope+modulation, where the amplitude of the carrier signal remains constant.
